To all whomitmwy cow/0am:-

Be it known that I, JEREMIAH BINGHAM, a citizen of the United States of America,

residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Machines for Accurately Alining and Closing Roll- Holding Cages for Roller-Bearings, of which the following is a specification, reference being had therein to the accompanying drawm s.

lhe invention relates to the manufacture of roller bearing cages of that type in which the rollers are housed in individual cells, said cells being secured to connectors which hold the same 1n predetermined relation. It is the object of the present invention to secure accurate alinement ,of the individual cells when rigidly attached to their connector, so that in the subsequent operation the rolls in said cells will be accurately alined.

To this end the invention .comprises the novel construction as hereinafter set forth.

' In the drawings:

Figure 1 is a central longitudinal section through the machine;

Fig. 2 is a plan view thereof;

Figs. '3 and 4 are respectively a plan v1ew andside elevation of the cage which is closed and alined by the machine;

Fig. 5 is a detail plan view showing the clamping member in a different posltion of adjustment.

The cage which is to be closed and alined by the machine comprises a series of indivldual roller holding-cells A, each containing a roller B havin a conical body, and enlarged head; C an D are connector rings at opposite ends of the rolls and cells, said rings being grooved to engage end flanges E on the individual cells and being apertured .for engagement with tongues F. on said flanges, which are clenched over said rings.

With the construction as thus far described, it will be impossible to secure such accuracy of workmanship as to hold all of the bed and resting upon a resilient yield able support, such as a rubber pad. Surrounding the central bearing J is a series of radlally-arranged clamping members M, said members being mounted in an annular radially-slotted member N arrangedconcentrio with the members H and I. The member N is yieldably supported upon rods 0 which pass through the bed and also engage the resilient yieldable pad. Each of the clampmg members M is fashioned at its inner end with a concave bearin M for engagmg an individual rollerolding cell, said bearlngs being inclined to corresopnd to the taper of the cell and the roll contained therein.-

is an annular member mounted upon the bed so as to be rotatively adjustable thereon concentric with the axis of the members H and I. This member P is preferably secured by a shouldered engagement P with the bed and a securing ring member P which-engages a peripheral groove in'the member P and is itself secured to the bed by clamping screws P Thus by the bearings P and P the rim P may be held accurately centered with t e members H and I. Q, are cam members secured to the ring member P, preferably by being provided with shanks Q engaging radial apertures in BEARING COMB ANY,

the ring and secured by clamping screws Q engaging said shanks. This arrangement for wear by the use of shims. R is a movable, die member concentric with the members H and I and fashioned to engage the upper connector ring. S is a clamping member arranged concentrically within the die.

member R and yieldably pressed by a spring S. T is an outer clamping ring member surrounding the die R and yieldably pressed 'by s rings T. The member T has a tapering' ower face T for engaging a ta ering opposed bearing N, onthe member so as to maintain the accurate alinement of these two members.

With the construction as describedin operation, the die member R is normally withare also adjusted radially outward so as to drawn and the radial clamping members N provide clearance for the placing of the roller-holding cage in engagement with the central bearing 1. The cage is first loosely assembled by the engagement of the tongues F of the individual roller-holding cells with their connector rings C and D, and the bending over of said tongues a sufficient-distance to prevent disengagement. The engagement is not, however, one which will hold the cells from a limited adjustment in relation to the connector rings.

' lVhen the cageis placed upon the bearing I, the rolls in the individual housings will rest with their end-thrust bearing surfaces against an annular shoulder I on said hearing and their tapering portions in line contact with the conical hearing I. The alinement of the rolls will not, however, be accurate when thus initially placed in position and to obtain accurate alinement the members M must be moved into engagement therewith. Also these members M must be placed in registration with their respective roll-holders. Registration is effected. by permitting the-initial movement of one of the jaw-members M into engagement with its individual cell, which will automatically cause a proper rotative adjustment of all of the jaw-members to produce registration. To thi end and also for the purpose of withdrawing the clamps atthe completionof the operation the member P is provided with an inwardly-extending flange U having cam slots U therein for engaging pins M on the clamping members M. One of these pins,

M is longer than the others and may beused as a handle for actuating the one clamp which is to effect the registration.

After the registration of the clamps with the roller-holding cells, the ring member P is rotated by means of an operating handle V, which will cause all of the cams Q to simultaneously press inward all of the radial clamping members M. The concave bearin s upon these clamping members will force t ecells and rolls into accurate alinement and will also clamp the arts in this position against accidental placement. The closing movement for rigid attachment of the connector rings with the housing is effected by the depression of themember R, this being secured to the plunger of a suitable press. Durin the downward movement, the member will first be pressed b the spring S against the connector ring (Z holding the same in position, while the die member R is pressed thereagainst and against the tongues F. This will rigidly connect these parts, and as they are held during the operation in absolutely true alinement, such alinement will be subsequently maintained. At the completion of the clenching operation for the upper connector ring C, a further downward movement of the die member R will carry with it the members I, M and N, these being yieldably supported -by the rods L and 0 upon the resilient yieldable cushion. -During this final movement the tongues F, engaging-the lower connector ring D,'-will be clenched, the alinement of the rollers and cells being still maintained. After the upward movement of the plunger the handle V may be operated to release all of the clamps M, after which the closed cage may be removed and the machine used for another operation. v

What I claim as my invention is:

1. The combination with means for holding a loosely-assembled series of individual roller holding cells and a connector therefor, of means for accurately alining said cells, and means for rigidly attaching said cells and connector while thus alined.

2. The combination with means for holding a loosely-assembled series of individual roller holding cells and a connector therefor, of means for clamping the individual cells in accurate alinement and dies for pressing said connector andcells to rigidly attach the same and maintain such alinement.

3. The combination with means for holding a loosely-assembled series of individual roller holding cells and a connector therefor, of means for limiting the radial movement of said cells to aline the same circumferentially, radially adjustable means for engaging the individual cells to aline the same longitudinally, and dies for pressing the cells and connector to rigidly secure the same' ing said cells and connector to rigidly 'secure the same while thus clamped in accurate alinement.

5. A device for alining roller holding cages having a series of individual roller holding cells and ring connectors at opposite end thereof, said device comprising a conical bearing having an end thrust shoulder for engaging the sides and ends of said rolls, a series of radially-adjustable clamping members for engaging the individual cells and rolls and holding the same against said conical member and in accurate alinement, means for pressing the connector at one end of said cage against said cells to rigidly secure the same in accurate alinement, means permitting the yielding of said conical bearing and radial clamping means under the further pressure of said pressing means, and a stationary die against which said opposite connector is pressed to rigidly secure the same to said sides.

6. A device for the purpose described, comprising a central bearing and radially adjustable clamping members for initially alining the individual roller holding cells, a yieldable support for said bearing and clamping means, a die for pressing against one end of the cells to, rigidly attach a connector thereto against the resistance of said yieldable. support, and a die forrigidly securing the connector at the opposite end of said cells upon the yielding of said bearing and radial clamping means.

7. An alining clamp for roller holding cages, comprising a central conical bearing, a series of radially movable clamping members arranged around said bearing, each having a concave inner end for engaging and alining an individual roller holding cell, means for adjusting one of said radial clamping members to register and enga e the same with one of the individual celi,

I and means for simultaneously adjusting the remaining clamping members to clamp all of the cells in accurate alinement.

8. An alining clamp for roller holding cages, comprising a central conical bearing,

a series of radially arranged clamping memmembers, and means for initially operating one of said clamping members individually to register the same with the roll to be clam ed.

9. 'lhe combination with a bed, of an annular die member rigidly mounted thereon, a clamping member yieldably supported above said bed, comprising a central conical bearing, a series of radially-arranged clamping members, and'guides for holding said members in accurate relation to said central bearing, a circumferentially adjustable member on said bed, cams on said circumferentially-adjustable member for simultaneously actuating all of said radial clamping bearings, and a movable annular die member on the opposite side of said clamplng means from said stationary annular die member,'
